Description:
Cartridge heater is a kind of heating elements made of MgO powder or MgO tube, ceramic cap, resistance wire(NiCr20/80). It is used to heat in plastic injection moulds, dies, platens .
Cartridge heaters are most frequently used for heating metal parts by insertion into drilled holes. For easy installation, the heaters are made slightly undersize relative to their nominal diameter.
GME produced cartridge heater sprovide superior heat transfer, uniform temperatures, resistance to oxidation and corrosion and long life even at high temperatures.Our experience ensures that the performance and life expectancy of our cartridge heaters supersedes the cartridge heater of other companies.
